Hms challenger expedition first oceanic expedition dedicated to scientific research. Density is a key concept for understanding the structure of earth. Density is usually expressed in grams per cubic centimeter (g/cm3) Determined by studying seismic waves generated by earthquakes + earth"s magnetic field. Surface waves cause most of property damage. Body waves are used to analyze the earth"s interior structure. P + s waves (move through earth) P: primary; compressional ( travel twice as fast as s ) Earthquakes generate seismic waves that provide evidence for the earth"s structure. Waves passing through a homogeneous planet would not be reflected or refracted. In a planet that becomes gradually denser, the waves would bend along evenly curved paths.
